dc.description.abstractThe Bor Plain lies in a round-shaped flat basin in the southern part of the Central Anatolia. It is located at the southeastern end of the Tuzgolu Fault Zone which is the NW trending, active normal fault zone and extends between the north of the Tuzgolu (Lake Tuz) at NW and at Kemerhisar (Nigde) SE. According to geomorphologic and geologic studies, this plain was occupied by lake during the Pleistocene. The first high lake level (terrace) and the latest high lake level (terrace) were determined at 1170-1150 m and 1110-1100 m, respectively. Pleistocene and Holocene alluvial and lacustrine deposits are composed of claystone, sandstone, mudstone, limestone and paleosol units. These units contain mostly calcite and clay minerals (palygorskite, smectites, illite and chlorite), and lesser amounts of quartz, phillipsite, cristobalite, feldspar, plagioclase, goethite and, muscovite. The results of this study are compared with the results of sedimentologic and dating obtained from Konya-Eregli Plain. According to this comparison, 1 the latest high lake terraces were dated 23,000 to 17,000 yr BP. The high lake level was changed, 2 sandy level with carbonate determined in stratigraphy indicates that a dry phase dominated after 17,000 yr BP, and 3 black and brown muds indicate that the shallow freshwater lacustrine phases and sandy levels were formed between 12,500 and 1100 yr BP during late glacial stage. Paleosols, muddy levels and shallow lake deposits were formed in the environment of the Holocene during 6000-5000 yr BP. Carbonate-rich sandstone and mudstone deposits show that this period was interrupted by the second drought in the latest stage. Temperatures have increased due to hot climate conditions and salinization has begun and been still ongoing. (C) 2015 Elsevier B.V. All rights reserved.
